。[Claims for Utility Model Registration] A bypass contactor is connected in parallel to a thyristor that controls a driving electric motor, and a bypass signal is sent to the thyristor through a first off-delay circuit having a sufficiently long duty time with respect to the mechanical delay of the contactor. In a motor control device for an electric vehicle, which is inputted as an on signal to the thyristor, the controller includes: a comparison circuit that compares a reference voltage with a terminal voltage of the thyristor; and a ring product circuit that receives the output of this comparison circuit and the output of the first off-delay circuit. and,
A second off-delay circuit having a shorter delay time than the first off-delay circuit receives the output of the ring product circuit, receives the output of the second off-delay circuit and the bypass signal, and transmits the output to the thyristor. 1. A motor control device for an electric vehicle, comprising: an OR circuit that generates an ON signal.
